Margaret Holloway is driving home, but her mind is elsewhere when she's rear-ended and trapped in the wreckage. Just as she begins to panic, a disfigured stranger pulls her from the car seconds before it's engulfed in flames. Then he simply disappears. Though she escapes with minor injuries, Margaret feels that something is wrong. Whatever happened, she didn't merely forget --- she chose to forget. And somehow, she knows deep down that it has something to do with the man who saved her life.

Solicitor Daniel Hunter is called to defend 11-year-old Sebastian, who has been charged with the murder of a young boy on a London playground. While examining Sebastian’s life in order to save it, Daniel can’t help but be transported to his own difficult youth spent in foster care --- a time when the one he trusted the most was the one who betrayed him.
